The Sanhuang Yujue proves that Yinfu is an imperial-esoteric transmission of the Three Sovereigns: its ‘jade secrets’ claim that true 阴符 is a restricted operative key for commanding yin-yang mechanisms, not open philosophy. Authority of practice derives from mythic sovereign lineage and sealed instruction, which concentrates efficacy by limiting and sacralizing access.
1) Treat major fate-altering rites as requiring precondition (precepts, purity, correct calendar), not DIY cleverness. 2) In BaZi, mark ‘sovereign’ structures (strong seal/officer with dao) as capacity for lawful command of 机. 3) Prefer fewer, higher-integrity operations over constant tinkering. 4) Keep oral/manual keys distinct from public text reading. 5) After operation, observe whether results match lawful timing; if not, recheck transmission conditions.
Differs sharply from Song philosophical notes by sacralizing secrecy and sovereign lineage. Differs from Quanzhen popularizing verse notes by restricting rather than democratizing; differs from Duren’s universal salvation ethos by elite-operative framing of power.
